To all whom t may concern 13e it known that I, JACOB l/V. Poiioiiiii, citizen of the United States, residing at Port ldfasliington, in the county of Tuscarawas end State of Uhio, have invented certain new and useful improvements in Lime-Spread ers, of which the following is a specification.

This invention relates to lime spreaders,

and has for its object to provide a simplel and durable structurel adapted to be moved over the ground and provided with n ieansfor automatically and evenly distributing lime during its travel.

` 1With this object in view the structure in i cjludes a hopper mounted upon a freine which in turn is supported upon a wheel mounted arie which traverses the length of the hopper. The hopper is provided iii its bottoni with-openings, and a slide is mounted npornthe bottom or' the hopper and pro-k videdjwitli openings which are adapted to he brought into register with the openings in the bottom of the hopper. Agitators vor eeders are arranged to reciprocate above the .openings inthe hopper bottom and slide, and

means is provided for reciprocating the same from the varde as the axle rotates.

For c. full understanding of the invention7 reference is to be had to the following description and accompanying. drawings in which: K

Figure I; is a perspective view oi the spreader; Fig. 2 a sectionall view of the saine taken through the hopperfroin end to end thereof; Fig. 3 is a top plan view of the some; F ig. Llis a .plan View of the slide.

Correspondingand like parts' are referred to inthe following description and indicated in all the views of the accompanying drawings by the saine reference characters.

x The spreader; includes a frame 1 to which is attached a draft tongue 2 and upon which is secured the drivers seat 3. A hopper/i and the hopper, 'an axle 6 being j ournaled in th bearings. The said axle traverses the iength of the hopper, and its intermediate portion is angular in cross section and spaced above the bottom or" the hopper while its end portions are circular to rotate in the bearings and project beyond the sides of the `traine 1. The bottom of the hopper is provided with several rows ofvopenings 7, the openings in one row being in staggered relation to the openings in the adjacentrow,v

is supported by the rear portion of the freine earings 5 extend through the ends oh' that is to sayI the openings in one row oocui opposite the intervals between the o enings in the adjacent row. The hopper is ,a so provided with a hinged to 8. ,v .Y

A slide 9 is arrange upon the bottom of the hopper between the front and rear walls thereof and is provided with openings 10 which are adapted to be broughty into register with the openings 7 in the bottom of the hopper. The slide is provided at itsedge with a lug 11 which extends through the rear wall of the ho per and a lever 12, ulorumed upon the baci; of the hopper, engages the lug 11. Therefore, itwill be seen that by swinging the lever 12 lthe slide 9 may be moved toward an end of the hopper whereby its openings v10 may bemoved into or out of register with .the openings 7 in the bottom of the hopper. VThe bottom of extended beyond and "T-shaped levers 14 are fulcrumed upon the extensions, eye bolts 15 being pivotally connected at their outer ends with A'the branches of the said levers. These bolts extend through the -eiids of the hopper and chain sections 16- are ffc'pnnected at their ends with the bolts, the said chainy sections being disposed over the openings 10 in the slide 9. The stems of fthe levers 14 project beyond the ends of the extensions 13 of the bottom of the hopper into the paths of radially disposed arms 17 which arescarried by the axle 5, and are equipped with rollers or rotary sleeves 17 at or near their extremities, as shown. .The arms 17 at one 'end ortion of the axle are disposed approximate y angles to the arms 17 at the other end rportion of the axle'. fixed to the axle 6 and supporting wheels 19 are jonrnaled upon the end portions ofthe the hopper is v axle, the wheels being provided with clutch hubs 20 which are adapted to engage the said clutch members 18. Springs 21 are mounted upon the end portions of the axle andbe'ar against the outer ends of the hubs 20 and serve as means for normally holding members 18V. rlhe, parts 2O and 21 are s0 arranged that when the wheels 19 turn as the spreader is moved in a forward direction the at right Clutch members 18 are the clutch hubs 20 in engagement with the clutch the ends thereof as at 13,

clutch hubs 20 engage `the clutch members 18 and cause `the axle to rotate, but shoiildthe wheels 19 turn in an opposite direction :the

axle G will remain at rest. This is what is generall known o as an. esoapement device iand is requeiitly usedin .agricultural ,nin-

chinesto permit the machines to be readily ,turned at the end sfof rows or at ,sides of a y by a' chain or other flexible device 23 with axle are at a right angle to the the openings l() and same to the ground.

the adjacent lever la so that the` parts may be' adjusted to bring the into coincidence vwith the arrival of the dropper in a position over the hills.

An apron 241.- is secured to the hopper at the front andthe rear of the same and -depends therefrom to the ground to prevent the wind reaching the dropping lime and blowing the same away from the spots it is intended to reach.

The operation of the spreader is as follows: When it is moved over the field the slide 9 is moved so that its openings i0 are brou ht into register with the openings 7 in the ottom of the hopper 4. Previous to this the said hopper has been supplied with a quantity of lime. During the forward movement of the machine the axle 6 is rotated as above described, and inasmuch as the axle traverses the length of the hopper it will have a tendency to keep the lime fromV packing or banking in the hopper. As tli axle 6 rotates the arms 17 come in contact with vthe end portions of the branches of the levers la and swine the said levers so that the agitator and feeder chains 16 are moved longitudinally over the rows of openings 10 in the slide 9. This movementon the part of thesaid chains will break up the lime and cause the same to iow freely through the openings 7 and l() and gravitate to the ground. By reason of the fact that the arms 1'( at one end of the arms 17 at the other end, the levers 14 are operated alternately, and consequently the chain sections 16 are caused to reciprocate along the slide dropping operation 9. TWhen the lever 14 at one end of the hopi per is' swung to an abnormal position the lever 14e at the other endis moved by the movement of the chains to anormal position, and vice versa.

The machine is composed of few parts which are simple in their construction and arrangement and will operate efficiently without liability to get out of order. Every time anarm' 17 strikes the end of a lever 14, the lever will be swung rearwardly so that a qaantity of lime will be pushed into will drop through the At the end of the field, the timing lever 224 may be actuated to pull rearwardly the lever it which is then in the forward position sothat the lever willy miss stroke on the next turn of the arm 17.

The feeding of the lime will thus be suspended while the machine is being brought into position for the return trip across the ield. rPhe rollers 17 minimize the we ar between the arms 1 7 and the levers 14.

Having thus described my invention, what is claimed as new is: i

l. A spreader comprising ground wheels, a hopper supported thereby and having openings in its bottom, T-shaped levers fulcrumed at the ends of the hopper and having their Vstems extending outwardly therefrom, agitators extending through the hopper over the openings in the bottom of the same and connecting the corresponding arms of the T-shaped levers at the opposite ends of the hopper, and means connected with the ground wheels to engage the stems of the levers and swing said levers alternately.

2. A spreader comprising a hopper, an axle traversing the length thereof and spaced from the bottom thereof, said hopper being provided in its bottom with openings, wheels supporting the axle, radial arms carried by the axle, levers fulcrumed at the ends of the hopper below the axle and having ends which lie in the paths of movement of the arms, and chains secured l to and extending between the levers and lying over the openings 1n the bottom of the hopper. i

3. A spreader comprlsing a hopper having `openings in its bottom, an angular axle traversing the length of the hopper and spaced from the bottom thereof, wheels supporting the axle, radial arms carried by the axle, adjacent the ends of thehopper, T-shaped levers fulcruined at the ends of the hopper and having end portions which lie in the paths of movement of the arms, and ilexible members secured to the levers and extending between the same and over the openings in the bottom of the hopper.

4. A. spreader comprising a hopper, an axle, traversing the length thereof and spaced from the bottom thereof, said hopper having openings in its bottom, wheels supporting the axle, radial arms carried by the axle beyond and adjacent the ends of the hopper, the armsat one end being disposed at an angle 'with relation to the arms at the other end, T-shaped levers fulcrumed at the ends of the hopper and having end portions which lie in the path of movement of the arms, and flexible members secured to the arms of the T-shaped levers and extending through the hopper and over the openings in the bottom of the same.

In testinion whereof I ailix my signature in presence o two witnesses.
